Heat Absorbing Glass Shortpass Filters
Heat Absorbing Glass Shortpass Filters
Heat absorbing glass shortpass filters reduce the heat transmitted through an optical system. They have high transmission in the visible wavelength region and absorb in the IR wavelength region, making them also useful as a shortpass filter. They are made with high quality Schott KG series heat absorbing glass.
